BOOKBINDING APPLIANCE.

ieiaico.

To all whom it may concern:

Be it known that I, Gnonon H. JENKINS, a'

I citizen of the United States, residing ati In the drawings:

Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bookbinding Appliances, of which the following is a specification. Y f

This invention relates to an appliance for evening and alining loose leaves and for compressing the edges thereof preparatory. to binding the same into=book form.

I have sought to provide'an appliance of the kinddescribed which will be simple, inexpensive, and eflicient for the purpose; to provide means for eveningand alining stacks of 1 leaves which'may vary in size;

and to, provide means for compressing the edges of the leaves to be bound,.the said means serving also as guides for a punching or :drillingdevice, and'b'eing so arranged as not v to interfere with the subsequent operation of. binding. The invention consists further in numerous other features of construction and combinations of parts, as will more fully hereinafterappear.

Figure 1 is a view in perspective from the rear side showing an embodiment of the present invention; I v

Fig. 2 is a plan view of. the guide and compression bar; 3

Fig; 3 is an enlarged detail of'one end of the guide and compression bar;

Fig. 4 is a detail of the lower guide plate I. and front edge of the same; i

Fig. 5v is a section through thebaseand one evener showing the means for advancing and holding the same in position 1; and

Figs. 6 and ,7 are modifications of the means shown infFig. 5.

In the present invention, I utilize a base 8- upon which a stack of leaves to be bound are laid in position. These leaves are alined and evenedup through the instrumentality of eveners 9, supported by members 10 se- Lcured to the rear side thereof. The' memberssecured to the laterally moving even- 5b ers carry each arearwardly extending arm teeth or serrations, as appears clearly in Fig. 5.- These arms 11 are arranged each to i 11, the'under. face of which is provided with lie'and fit slidingly within a slot 12 formed in the base 8, the sides of said armsengaging'with the walls of said slots to accuratelyguide the eveners in a straight line Specification ofletters Patent,

movement. The teeth upon the under side of each of the arms ll are arranged to en- Instead of the means shown in Fig. 5

for advancing the eveners, the arrangement illustrated .in Fig. 6 may be employed.

This differs only in that the armll; is carried forwardly of the block. so that a stackv of leaves when laid upon the base. lie directly over the arm, the weight of the paper pre- 1 venting its disengagement from the teeth 13.

I have. also'shown an evener 9 which moves in a longitudinal direction, or to and from the rearward and forward edges of the base 8. The means for accomplishing this moveiment may be the same as those described for the other laterally moving eveners, but I prefer to use means as follows. The supporting arm 11 is provided with a tongue 14 which projects into a slot l2 corresponding the rack and teeth, however, I utilize a threaded stem 15 which engages w th the tonguev14,.a wheel 16. for manipulating the same being located conveniently at the rear edge of the base 8. It is manifest that ro-- tation of this stein causes a positivemove- 'ment of this evener 1n a forward or rearward direction accordlng to-the nature of the manipulations effected. v Upon the forward edge of the base 8 1s a 1 plate 17 carrying upwardly extending posts 18 screw-threaded to receive each a'thumbnut 19. A plate 20 is also shown, corresponding closely in size to the plate 17 and 1 0 free to move vertically upon the posts 18. By providing a spring cl1p 21 at each end of theplate 20 to engagev with the thumb nut, this plate is maintained in elevated position whenever desired. I have shown a 105 plurality of bosses 22 extending upwardly from the plate 20 within which are c rcular openings 23 for purposes to be hereafter explained. Interconnecting each of these openings23 is a' slot 24 extending co'ntinu- 110 ou sly between the outermost bosses. -The plate '17 is similarly provided with a slot 24, v

with those forthe other arms 11. Instead of ij 355 a with this difference, however, that I do not deem it necessary to arrange enlarged openings 23, such as appear in the plate 20, but prefer to utilize a single widened slot of sub-.

stantially'equal length with the narrow slot in the plate'20. Beneath the plate 17 the base 8 is slotted as at 25, corresponding with the slot inthe plate 17, for purposes to be hereafter explained.

In operation, the used substantially as follows. The eveners are adjusted in position to receive the sheets of paper to be bound,'as well as the covers v to insertion in the present device, provided therefor, these being laid in place either a few or a large number at one time. The edges of the sheets which are to be bound are alined, with the plate 17 the evener adjacent the rear edge of the base cooperating for this purpose. By the means above described, the paper leaves are accurately squared and alined for bindingpurposes.

Thereafterthe plate 20 is brought down upon the edges of the leaves, and through manipulation of the thumb-screws 19, a compression of the leaves is effected. In the arrangement shown, a hand drill may be employed to bore through the edges of the paper the holes necessary for binding. To this end the drill is inserted into one of the openings 23, the advancement of the drill through the hole therein and through the block of paper thereunder being guided and determined by the boss which extends upwardly from the plate. By proceeding in this manner, the necessary number of holes may be provided in the edges of the paper.

.It is, of course, feasible to employ a multiple punch or drill press operated by suitable levers or power which can perform this 0 'eration, but in the emobdiment shown, a

simple and inexpensive boring outfit, such as the hand drill mentioned, is capable of bemg used. The openings 23 and bosses 22 are convenient to assist in guiding an implement,

but in some cases may found unnecessary, so that aplate 20, on which no such bosses are formed or which embodies a slot construction s mllar to that in the plate 17, may

perhaps be advantageously utilized;

--If the paper leaves to be bound are, prior with alining holes for binding purposes, the

' operation of drilling or punching holes in the manner described will not be necessary, of course. Suitable cords or other tyin means are strung through the openingsand tied permanently while the paper is still binding appliance is compressed, the sections of cord which overlie the outer edges of the paper slipping into position through the slots '24. Thereafter, the pressure is removed by manipulating the thumb screws in the proper .direction'and the leaves are removed in bound form as a separate book.

I claim: g 1.- A book binding appliance comprising a base on which a quantity of leaves may be stacked, the base being formed with a groove in the upper surface thereof, means for evening the leaves prior to binding consisting of a block arranged perpendicularly to I the base and movable thereon,.and a member secured to the block and arranged to maintain the block in perpendicular relation to the base, a portion of the said member being" arranged to lie within the'base groove-beneath the leaf stack, and means for securing the block in a selected fixed position of adjustment upon the base, substantially as described.

2. A book binding appliance comprising a base on which a quantity of leaves may be stacked, means for evening the leaves prior to binding consisting of a block'arranged perpendicularly upon' the base and movable with respect thereto, and a member arranged to maintain the block in perpendicu- I lar relation tothe base, the said member to binding comprising a block arranged per pendicularly to the base and movable there on, and a member arranged to maintain the block in perpendicular relation to the base secured-t0 the'block and in engagement with the base, the said member. being partially disposed beneath the stack of leaves'whereby the weight of the leaf stack serves to hold the member perpendicular to the base, and means for preventing retractive movement of the block upon the base, substantially as described.
